PROCESS OF BURNING B-RI CK.

. SPECIFICATION forming part of Letters Patent No. 410,245, dated September 3, 1889.

Application filed May 27.l 1889. Serial No. 312,307. (No model.)

T0 @ZZ whom, it may concern:

Be it known that I, JAMES M. J AMEsoN, of Los Angeles, in the county of Los Angeles, State of California, have discovered a new and useful Process of Burning-.Brick with all Kinds of Coal and with Brea or Crude Petroleum, of which the following is a specification.

The objects of said process are- First. To facilitate the burning by distributing the lire throughout the kiln and bring` texture and quality of the brick are regulated by the quantity of fuel used in burning, so

that any quality of brick can be obtained which may be desired.

In this process the kiln is formed either as an oblong square or in a circle, at the will of` the builder. The floor of the kiln is inclined a little from the outer edges toward the center to prevent it from spreading.

In the accompanying drawings, forming a part hei eof, Figure l is a View in elevation of a brick-kiln such as may be used in connection with my invention, showing the same as Fig. 2 is a cross-section, and Fig. 3 a vertical trans- Verse sectional elevation, illustrating the proposed manner of arranging the brick and interposed fuel within the kiln according Tomy invention. The letter A designates the walls of the kiln; a., the brick, which are placed in the kiln in zigzag rows, as shown in Fig. 2; b, the

` bed of fuel interposed between each layer of brick, and c the vertical interstices between the brick, also filled with fuel, which interstices are wider at the bottom of the kiln and decrease in width toward the top, as shown in Fig. 3. dindicates the inclined iioor of the kiln. The bricks are placed in the kiln in a zigzag manner, as shown in the accompany- There is but one eye or `flue near the end of the kiln, as shown in the diagram, whichis formed in the usual-way by extending the bricks in building. The kiln is surrounded by a permanent wall as a protection and to confine the heat within the kiln. The fuel 1s so used and applied throughout the kiln as to iill all the interstices and to cover the entire layer of the brick, so as to fol-n1 aA bed for the next layer of the brick, and so on to the top of the kiln. It is then closed in, as usual. The kiln thus formed when `iired requires no further stoking or attention until` it burns out, and the building and burning go'on together at the same time at the pleasure of the builder.

Having thus described inyinvention, I claim" as new therein and desire to secure by Letters Patent-A j The process in the manufacture of brick,

which consists in placing aiilayer of,` fuelthe floor of the kiln, which floor of the kiln is made to incline toward the center, placing terstices between the brick, iilling such intersticeswith similarfuel used to forin the irst layer, and covering the brick with said fuel to forni a bed for the second layer of brick,

`such as coal, brea, or crude petroleuin-upon i aga-in placing a layer of brick in'zigzag rows,

with interstices between the brick `and rows, upon the second bed of fuel, again filling such interstices with fuel and forming a third bed of fuel, and so on, alternately forming a bed of fuel and layer of brick in zigzag rows with interstices between the saine until the top of the kiln is reached, the interstices between the brick in each succeeding layer decreasing Witnesses:
